I dislike Cicero, cause he's a retard. Mostly on forums so admins fixed this nicely.
MUSASHI or MAGANDA, not sure which one is the spawnrushing bundle of sticks. Might be both of them. Or any other cav that rushes to the enemy spawn to couch spawners.
Shikoshugi Tiborur and Sir Agor for having been masters of bundle of sticksry when it comes to roofcamping.
Samfisher, cause he just blatantly spams with that hafted blade.
Ivani4, because he only has one mouse button and I need to hit him 5 times and when I glance once he oneshots me.
Jambi for being overpowered + archer = annoying as hell.
Those were the first few that came to mind.
